Background 

The electrofishing program described in this report adds to a data set begun in 
1956 when Dr. William C. Starrett of the Illinois Natural History Survey initiated an 
annual electrofishing survey of the Illinois River. The survey was supported from a 
variety of sources until 1985 when funding lapsed. Field work resumed in the fall of 
1989 with support from the federal program in sport fish restoration and the Illinois 
Department of Conservation, as a 5-year Survey and Investigation that extends until 
1994. 
Organizat ion and Contents of Report 

This report is organized according to the 6 jobs described in the Annual Work 
Plan for Segment 2, and covers the period 1 April 1990 to 31 March 1991. Although a 
comprehensive analysis of the entire 40-year data set awaits completion of the 5-year 
investigation in 1994, selected findings are highlighted in each year's annual report. This 
past year's major findings are reported as Job 6, Presentation of Results, and are briefly 
summarized below. 

The numbers, lengths, and weights of each species of fish caught in 1990 are 
presented by sampling station in Appendix A. The collections are presented in order by 
sampling date, and arc cross-indexed by location (see the index at the beginning of 
Appendix A). The Appendix is 76 pages long, and was not attached to all copies of the 
annual report to save copying and mailing expenses. Copies are available from the 
Principal Investigator, Dr. Richard E. Sparks, Illinois Natural History Survey; Mr. 
William Bertrand, Project Officer, Illinois Department of Conservation; and Mr. Jim 
Allen, Head of the Programs Section, Illinois Department of Conservation. Data are also 
available for IBM PCs on floppy disks in RBase for DOS.

Summary of Maior Findings in 1990 

The analysis this year focused on the upper Illinois River where the fish 
populations have been affected adversely in the past by waste discharges from the 
Chicago-Joliet metropolitan area, but where game fish populations seem to be recovering 
as waste treatment improves. 

The condition of largemouth bass, smallmouth bass, white bass, and carp, as 
measured by relative weight, Wr, improved between 1982 and 1985 in the upper Illinois 
River, but declined by 1989. Wr of the three basses were all above 1.0 by 1985. In 
contrast, the Wr of channel catfish peaked earlier, at slightly better than 1.0 in 1983, and 
has since declined to just above 0.8. 

Another indicator of a long-terra improvement is the development of a sport 
fishery for sauger in the upper Illinois River. Sauger first appeared in substantial 
numbers in our catch in 1979 in the upper river, confirming that return of the sauger is 
a relatively recent event that appears to be associated with water quality improvements 
made during the decade of the 1970's, starting with the Clean Water Act of 1972. 

Although the increased catch of sauger and the improvement in Wr of 4 of 5 
species over the last 10 years are encouraging, the decline in Wr values between 1985 and 
1989, and the further decline in 1990, are worrisome, particularly since 2 other agencies 
have obtained similar findings. The Illinois Department of Conservation has noted the 
same decline in several species of game fish in their electrofishing collections from the 
river in 1989 and 1990, and Southern Illinois University reports a decline in the Wr of 
sauger (personal communication. Dr. Roy Heidinger, Professor of Fisheries, Department 
of Zoology, Southern Illinois University, Carbondale, Illinois, 9 April 1991). 
Representatives from all three agencies met in Springfield on 9 April 1991, with 
representatives from the Illinois Environmental Protection Agency and the Metropolitan 



Electrofishing survey 30 May 1991 Page 3 

Water Reclamation District of Greater Chicago to discuss possible causes of this decline 
and to coordinate a more intensive sampling of water quality in 1991. Thus these data 
sets, including the set from this project, F-101, have demonstrated their utility by 
providing early warning of a potential problem. It may be possible to identify the cause 
and take corrective action before the condition of the fish populations in the upper 
Illinois River revert to the lows that were characteristic of the 1960s. 

Job 1. Preparation of Equipment 

All old equipment was checked and refurbished as needed. A second timer was 
added to the control console so that the driver does not have to look to the side at the 
switchbox to see how long the generator has been running. The old Homelite generator 
was tuned up and used throughout this sampling season. We measured the voltage to each 
electrode at the beginning and end of each sampling run to ensure that the output was 
consistent. 

The new MultiQuip generator was modified to serve as an emergency backup, but 
did not have to be used this year. Mr. K. Douglas Blodgett constructed a resistor box to 
reduce the voltage of the MultiQuip to the same level as the old Homelite. He also added 
safety features recommended in the electrofishing school taught by the U.S. Fish and 
Wildlife Service. 
Job 2. Training Staff 

Mr. Phillip Moy, Mr. Eric Hopps, and Ms. Ruth Sparks read the procedures manual 
and practiced with the equipment in the Illinois River at Havana, under the supervision 
of Dr. Richard E. Sparks and Mr. K. Douglas Blodgett. All staff had previously taken a 
Red Cross First Aid and CPR course.

Job 3. 1990 Electrofishing 

Water levels in the Illinois River were high much of the summer (Figure 1). By 7 
September, water levels in the upper river were close to the mean low river stage, so we 
began electrofishing that part of the river first. AH 26 stations on the Illinois River and 
the one station on the Mississippi at Brickhouse Slough were sampled by 28 September 
(Figure 2 and Table 1). 

Small fish which could not be positively identified in the field were preserved in 
formalin and brought back to the Laboratory. They were tranferred to alcohol and 
identified during the winter. 

Several interesting observations were made during the course of the field work. 
Yellow perch were extremely rare in collections made years ago, but this year 2 were 
captured at Ballard Island Chute. Most of the goldfish had the "wild type" bronze 
coloration, rather than the white, black, or bright orange characteristic of the "dime 
store" varieties. The bright colors are probably rapidly selected out of the population 
now by predators, whereas the predators were virtually absent from the upper river 15 
years ago. We saw some "knothead" carp, but the incidence is much lower than formerly. 
Erosion of fins and barbels on the ventral side of bottom-dwelling fishes is still a 
problem, indicating some sort of stressor associated with the sediment. An anomalous 
collection was made at Hennepin Island Chute, where only 2 fish were taken in 0.33 
hours of electrofishing. The equipment seemed to be working properly, and the 
abundance of fish in collections made at the stations above and below Hennepin were 
about as expected. The generator labored when the electrodes were switched on (as it is 
supposed to under demand) and the voltages to each electrode were in the normal range. 
It is possible that fish had abandoned the chute because of some noxious material. No 
dead fish were observed on the shoreline.

Station 27 is in the Mississippi River, just below the mouth of the 
Illinois River. Stations 1 and 2 are in the Des Plaines River, 
which joins with the Kankakee to form the Illinois River. In this 
report, we define the upper reach of the Illinois Waterway as 
beginning at River Mile 190, just upstream of Peoria. Stations 1 
through 12 are in the Upper Illinois Waterway.

Another discouraging observation is the degree of sedimentation. It was 
impossible to fish the exact locations sampled in the past at Ballard Island Chute and 
Detweiller Marina because the boat became stranded. These 2 stations will have to be 
abandoned and alternative sites picked for 1991. A third station, Turkey Island Chute, 
changed from a deep to a shallow chute approximately 15 years ago, when it apparently 
was filled with sandy dredge spoil. The on-site dredge spoil inspection teams will 
probably avert another Turkey Island Chute. However, gradual filling of some of the 
remaining side channels and backwaters will continue unless remedial action, such as 
proposed for a few locations under the Environmental Management Program, is 
undertaken. Hurricane and Diamond Island chutes in the lower Illinois River remain 
deep and generally have good fish populations year to year. These chutes have a fairly 
uniform width and moderate current velocity, and appear to be self-scouring. The same 
design might be self-maintaining if copied in other parts of the river. 
Jobs 4 and 5. Database 

Mr. Robert Illyes has made considerable progress at the Survey's main office in 
Champaign on merging the historical data sets and making them available in an RBase 
format that will run on an IBM PC. This has not been an easy task because the coding 
differs markedly between the Starrett-Sparks data set and the set collected by Kenneth 
Lubinski. During the past 15 years the mainframe computers and the software used for 
data analysis at Champaign have changed at least twice, adding further incompatibilities 
and complications. 

The historical data are being converted to coding and formats that are consistent 
with this project (F-lOl-R), which began in 1989. 

Mr. Illyes is developing checking routines that will find obvious errors, such as a 
1-inch fish that is listed as weighing 2 pounds, but it may still be necessary to complete 
one more round of verification by laboriously checking printouts against the original 



Electrof i&hing survey 30 May 1991 Page 11 

field data sheets. 

Job 6. Presentation of Results 

Results from this project were included in a talk presented at the 29th annual 
meeting of the Illinois Chapter of the American Fisheries Society in Urbana, Illinois on 6 
March 1991, and were presented at a meeting of fishery biologists and environmental 
engineers concerned with the relationships between water quality and the status of fish 
populations in the Upper Illinois Waterway in Springfield on 9 April 1991. The general 
increase in relative weight of 5 species of fish, including 4 sport species, from 1982 to 
1985 was good news for the fishery managers and water quality managers, as was the 
appearance of substantial numbers of sauger in the catch, starting in 1979. However, 
recent declines in relative weights of the same species, including sauger, prompted the 
Illinois Department of Conservation (IDOC) to call the meeting in Springfield, which was 
attended by Dr. Sparks and Mr. K. Douglas Blodgett from the Illinois Natural History 
Survey, and by representatives from the Illinois Environmental Protection Agency, the 
Cooperative Fisheries Unit at Southern Illinois University, and the Metropolitan Water 
Reclamation District of Greater Chicago. The information on relative weights and 
sauger catch that was presented at these meetings is summarized below and in the 
accompanying figures. 

Relative Weight. Wr. The standard length-weight relationships used for comparison with 
the values from the Upper Illinois River were taken from sources cited in Murphy, Willis 
and Springer (1991) and listed in their Table 1: Stephen (1978) for carp, Anderson (1980) 
for channel catfish and smallmouth bass. Brown and Murphy (in press) for white bass, 
and Wege and Anderson (1978) for largemouth bass. 



Electrofishing survey 30 May 1991 Page 12 

The relative weights of white bass, smallmouth bass, and largemouth bass 
increased to values greater than 1.0 between 1982 and 1985 (Figure 3). The greatest 
increase occurred in smallmouth bass, whose Wr values went from approximately 0.8 in 
1983 to 1.3 in 1985. No electrofishing was done from 1986 through 1988, so we do not 
know what happened to the Wr values in this interval. However, the values for all three 
species were lower in 1989-1990 than in 1985. Changes in weight-length relationships, 
including Wr, can reflect changes in the food supply, water quality, habitat quality, or in 
the length range of the fish. One might speculate that these three species may show the 
same pattern because they have similar feeding habits: they consume invertebrates when 
young and graduate to larger prey, primarily fish, as adults. 

The hypothesis that the quality or abundance of forage for adult sport fish might 
explain the common downward trend does not explain why the common carp, a bottom- 
feeding omnivore that is capable of consuming detritus, shows the same pattern. Also, 
the channel catfish shows a unique pattern: its Wr value peaked in 1983, declined 
through 1985, and is at an intermediate level in 1989-1990. The channel catfish is an 
omnivore that consumes benthic macroinvertebrates, but will also take small fish. With- 
out information on populations of forage organisms, including benthic macroinverte- 
brates, it is virtually impossible to test the food deficiency hypothesis. 

There is a suggestive negative correlation between Wr values and ammonia 
concentrations in the Upper Illinois River (personal communication, 9 April 1991, Mr. 
William Bertrand, Streams Program Administrator, Illinois Department of Conservation). 
The un-ionized form of ammonia is toxic to fish and other aquatic animals. The 
concentration of municipalities and industries in the Chicago-Joliet discharge ammonia, 
as well as nitrogen-containing organic matter that accumulates in sediment deposits and

could form ammonia under anaerobic conditions. Again, more information is needed to 
determine whether this correlation is coincidental or causal. Virtually any pollutant that 
occurs in sewage or industrial effluent will occur in higher concentrations in the upper 
river, near the sources, than farther downstream, so ammonia is only one suspect. 
In order to determine whether the slight declines we observed in Wr values 
between 1989 and 1990 might be attributable to different length ranges of fish captured 
in the two years, the weight-length values were plotted and visually examined (Figures 4- 
8). With the exception of smallmouth bass, the lengths in the two years overlap and are 
in the same range. Too few smallmouth bass were captured in the Upper River in 1990 
to make a valid comparison of Wr values (Figure 8). 

Saueer. Although the sampling design of the long-term electrofishing program is biased 
against sauger and walleye (no tailwaters are sampled and no night electrofishing is 
done), it is gratifying to note that the increased catch of sauger, starting in 1979, is 
verified independently by the IDOC sampling program and by the development of a sport . 
fishery for sauger in the Upper Illinois River (Figure 9). Fish sampling begun in 1990 as 
part of the Long Term Resource Monitoring Program (LTRM) likewise shows that a 
substantial population of sauger occur in the La Grange Pool of the Illinois River, just 
below the navigation dam at Peoria (Figure 1). Although the increased catch of sauger, 
like the Wr values, show»an improvement in the fish populations that may be related to 
improved water quality in the last decade, the recent decline in numbers of sauger and in 
Wr since 1985 may be an early warning of impending problems, and an incentive to 
determine and correct the causes.

Figure 9. Total number of sauger collected during annual electrofishing 
surveys of the Illinois Waterway. The total hours fished were 
roughly the same each year. Zeros indicate that electrofishing was 
conducted and no sauger were taken. NF means that no electro- 
fishing was done, either because of high water or lack of funding.
